Application filed March 27-, 1928. Serial No. 265,198,.

The present invention relatesto harrows and elod' crushers, and aims to provide a novel and improved device for crushing or breakingup the clods or lumps of dirt when plowmg.

The invention embodies an attachment for the wheel of a tractor used for pulling a plow or plows, and adapted to work on thesurface of the plowed ground, in order to break up the lumps of dirt during the plowing operation.

A further object of the invention is to provide a device of the character indicated which will pulverize and level the plowed ground while it'is' damp, and before it becomes hardened by the sun and wind. which will keep or provide a mulch at the surface of the ground in order to retain the moisture essential to plant growth, which will enable the tractor to move on solid ground while harrowing, and which'will save power and wear and tear on the tractor.

Another object of the inventionis the provision of a novel attachment'for a tractor wheel for the purpose indicated.

With the foregoing and other ob ects 1n view,,-which will be apparent ilS'illlG ClGSCllP- tion proceeds, the invention resides in the construction and arrangementof parts, as

hereinafter described and claimed,'i.t being understood tl at changes can be made within the scope of what 18 claimed. without depart- 1n g from the spirit of the invention.

The invention is illustrated in the accom- J panying drawing, wherein Fi urel is'a rear view of a tractor havin theattaclunent applied, the attachment and a portion of the tractorwheel to which it is applied being shown in section. 4

Fi 2' is a side elevation of the attachment on the tractor Wheel. v

The'device may be-constructed to heapplied to any suitable tractor usedfor pulling a plow or plows. The tractor. shown in Fig.

, 1. has the right and left rear tractor wheels'T posed in annulararrangement. and have inconical form in order that the bars 13will signature.

wardly extending radial terminal portions 14 extending across the rings 11 and fastened to said rings by means of bolts 15 or. other suitable securing elements. The terminals 14: have a series of apertures'lG to receive said bolts, in orderthat the bars may be adjusted to different diameters, so as to properly engage the ground. V Crossed diagonal braces 17 are provided between the rings. 10 and 11,in order to brace the structure, and the terminals of the braces may be held by the corresponding bolts 15;

The attachment is of tapered or frustoln'eak up the lumps or clods of dirt, thereby harrowing or pulverizing the soil simultaneou'sly with the plowing operation. The attachment is pref'erably'of alength to correspond with the number of plows pulled by the tractor,-in order thatthe attachment will operate over a strip a of ground equal to the width of the strip turned by the plows; Y

Having thus described the invention, what is claimed as new is -1. A harrow attachment for a tractor wheel comprising inner and outer rings, bars connected tosaid rings for radial adjustment and to engage the $011.5 diagonal braces connected to said rings,- and means for attaching one of said rings to the Wheel of a tractor.

2; A harrow attachment for a tractor wheel comprising inner andflouter 1'iiigs, an l annu-- larset' of bars having inwardly extending radial terminals adjustably attached to said 3. Aharrow attachmentfora.tractor'wheel comprising mner and outerrmgs, an annu-- lar set'of bars having inwardly extending 1 00 radial terminals aclpistably attachedto said rings," diagonal braces between said rings 7 and means for attaching one of sa d rings to the wheel ofa tractor.

4'. A tractor wheel attachment comprising 105 inner and outer rings; an annular set of bars 'offrusto-conieal form having inwardly ex tending radial terminal portions extending across and; ad ustablysecured to said rings.
